Here's my meal plan for feeding a family for under £100 p/w.
Breakfasts - Aldi wheat and blueberry things (they look like shredded wheats - I CBA to go into the kitchen to find out what they're actually called.
Lunch - DD1 - £12.50 on her pre-pay account with the school
Lunch - DD2 - Aldi's halzenut and chocolate spread on white bread, monster munch (from Iceland which is next door to Aldi), apple, Aldi squeezy yoghurt, Aldi fruitshoot, Aldi's version of Jaffa cakes x 3.
Lunch me - Aldi Frozen sauasges or an egg in two slices of bread, unless I am at work where I eat free or college, where surprisingly I also eat free. I'm at college p/t - mostly mornings - I get £3 a day and a voucher for a free breakfast. I have to pay £12.50 a week for DD1 who is in school full time. This makes no sense to me.
Lunch dog - free meat scraps from work
Dinners
Salmon fillet, baby new potatos in mint and butter sauce, baby carrots, peas, broccoli.
Pizza (Aldi stuffed crust), crispy chicken strips (Iceland - BBQ flavour), Spicy wedges (Aldi), coleslaw (Aldi)
Veggi Chilli and rice (made with Aldi chillli sauce and aldi tinned pulses)
Chicken stir fry (if and only if the dates on Aldi's stir fry veg are long enough to last until Sat when we don't have DD2 who does not like stirfry) or Aldi frozen duck with pancakes, cucumber strips and Iceland mini kofta kebabs.
The rest of the time we eat dinner at family or eat from the tin cupboard or freezer. Sadly, my freezer does not magically produce food, I have to buy it. I generally buy chicken nuggets, an extra pizza, some pastries (Iceland Gregg's range if they are on offer, whatever Aldi has of they're not), tins of beans, hotdogs and spaghetti, frozen sausages, extra yoghurts and apples, Aldi's version of nutrigrain bars and bananas.
Bought from Aldi and Iceland this all comes to around £50 including dog food, sanitary wear and cleaning products but not toiletries which I get from a beauty supply store with my trade card.
